Ensure uninterrupted power and protect your essential systems with this Automatic Dual Power Transfer Switch (ATS)/ Change over switch. Designed for seamless automatic power transfer between an off-grid renewable energy source (solar, wind, hydro) and a backup power supply such as a generator or the grid, this intelligent switch guarantees reliable operation during a power outage or battery depletion. Ideal for home energy systems, RVs, boats, cabins, and critical systems requiring constant electricity.

Reliable Automatic Power Transfer for Backup Energy: 

This power transfer switch automatically prioritizes battery/inverter power and only switches to grid or generator when battery voltage is low. Once the battery is recharged, the ATS instantly switches back—providing a smart switchover without interruption.

Built as an opposite UPS (Uninterruptible Power Supply), it extends battery life, optimizes renewable energy use, and supports business continuity and emergency power needs in remote or mobile settings.

Features:

• Automatic Power Transfer: Seamless switchover between primary and secondary power sources without system downtime

• Battery Priority Mode: Inverter AC from solar/wind/hydro-powered batteries is used first; switches to generator/grid only when needed

• Rapid Transfer Times:

  • Inverter to public power: ≤ 10ms

  • Public power to inverter: ≤ 16ms

  • No flicker, no interruption—ideal for sensitive electronics and critical systems

• Energy-Efficient Operation: Save up to 30% on your energy bill by maximizing the use of renewable sources

• Battery Protection: Prevents over-discharge, extending battery lifespan and ensuring availability during emergencies

• User-Friendly LCD Display: Monitor power supply status, grid availability, battery voltage, and more

• Simple DIY Installation: Plug-and-play design; no need to cut into factory wiring—ideal for boats, RVs, and mobile setups
